In traditional legal and case management systems, there are inherent issues related to trust, transparency, and security. Sensitive case data is often stored in centralized systems, making it vulnerable to tampering, unauthorized access, and data breaches. This can result in loss of trust, inefficiencies in managing cases, and limited accessibility for the stakeholders involved in the process.
CaseLedger addresses these challenges by leveraging blockchain technology and Zero Trust Architecture (ZTA). The platform ensures that all case records are immutable and transparent, removing the risk of tampering. Additionally, ZTA, along with role-based access controls, ensures that only authorized users can view or modify case information, significantly enhancing security, traceability, and accountability.
Role-Based Access Control (RBAC) in Blockchain:
One of the significant hurdles was implementing fine-grained role-based access control within a decentralized framework. Blockchain doesn't natively manage user permissions as traditional systems do, so we had to create a custom access control mechanism using smart contracts. With this solution, we can define and enforce roles for various legal stakeholders such as lawyers, judges, and clerks.
Implementing Zero Trust Architecture (ZTA):
Ensuring a Zero Trust Architecture within a decentralized app was challenging. We sought to introduce JWT (JSON Web Token) for authentication, mTLS (mutual TLS) for secure communication between services, and dynamic access policies for granting or denying case file access. Our design forces continuous verification of user identity and privileges before granting access to any case data.
Optimizing Blockchain Storage:
Managing large documents and files on-chain can be expensive. We had to optimize the storage of case files by utilizing IPFS (InterPlanetary File System) for decentralized file storage while storing only critical metadata on-chain. This improved performance while maintaining decentralization and immutability.
User Experience & Access Management:
Handling access management for a wide variety of stakeholders in a decentralized manner was complex. We built a system to dynamically manage the access rights of different users (e.g., lawyers, plaintiffs, judges), ensuring that only the appropriate stakeholders have access to specific cases.
